I guess yeah, it would be far more practical for the NWO to weaken the US from within rather than spending to build up the other nations such as China and Russia. I had always thought it would be unfair that foreign troops would be used to police the US, to become cannon-fodder to the rednecks and militia.

The scenario you spelt out--though I meant no ill to American people--does make some karmic sense, if you believe in karma.
